Since firewire is going out of style, I could probably get more selling the 828mk3 now than I would a few years down the road. I'm worried when I finally upgrade computers (which honestly isn't for awhile still), I won't have a firewire port to work with. The Duet 2 has two mic pres and thats all I really need for inputs. I occasionally use the two mic inputs to record, but thats about it. I hardly do anything with the inputs and outputs on the 828mk3. This gets tedious after awhile (I've notified MOTU a few times about this but it still hasn't been fixed)
I have to go into the system preferences and switch it manually every time. Since OSX 10.7, OSX doesn't automatically switch audio out to the 828mk3 when its switched on. But here's my reasons for considering the switch:
My 828mk3 is the original firewire version, and I'm a bit worried about its future life with new computers. I'm working exclusively in Digital Performer every day. I'm considering switching from my MOTU 828mk3 to something a little more easy to work with and future proof - in this case, the Apogee Duet 2.
